Book Description
This research aims to study the dynamics of charged ions moving through a charged system, and the interactions they have on each other. The underlying principles that govern the movement through a polyelectrolyte system can give insight into biological fibers such as actin, muscles and neurons. This investigation seeks to: developing an electrolyte-based system that exhibits movement, understanding the driving forces of movement from a macromolecular perspective, and developing an actuating system based on the parameters developed therefrom. Understanding fundamental polyelectrolyte behavior is the key to inducing physiological movement mimicking muscles and neurons. Previously, we have verified that poly(acrylate) gels exhibit electrical potentials in the range normally afforded by living cells. However, we have unexpectedly found that poly(acrylate) gels in aqueous solutions of monovalent salts such as KH2PO4 in a narrow concentration range (ca. 8-16 mM) leads to a softening of gels without measurable volume changes. The electrical potentials of the gels, using standard electrophysiological methods, show an abrupt increase in gel potential (to ca. -100 mV) with no appreciable macromolecular size change or mechanical transition, seen by elastic and compressive modulus. Magnetic resonance imaging experiments reveal a change in water mobility in the same transition region. Small angle neutron scattering also does not demonstrate a structural change in mesh size at this transition, suggesting a change is due to the cation and anion type and association with the chain. Through this, we predict the counter ions have a larger factor in polyelectrolyte theory than previously known. By utilizing this transition region, we can induce facile movement through a polyelectrolyte gel with salt solutions and active movement with electrical current. Generating movement of the whole gel solely due to ion concentrations of mono- and divalent salt, ion interactions with the polymer, and ion interactions with itself lays the central foundation on which to build a model from. Based on our understanding of polyelectrolytes, we have found the optimal conditions to induce movement and a phase transition through the gel passively. Electrical stimulus is tuned to actively induce movement in physiological conditions.

Book Description
Polyelectrolytes and their Applications is the second volume in the series 'Charged and Reactive Polymers'. The important areas of polyelectrolyte applications, i.e., biomedicine, water purification, petroleum recovery and drag reduction, are pre sented along with discussions of the fundamental principles of polyelectrolyte chem istry and physics. This book should be of interest to scientists such as physicians, biochemists, polymer chemists and chemical engineers involved in applications of these materials. The first part of the book is devoted to the basic properties of polyelectrolytes in general, namely to the factors influencing the chain conformation of charged polymers in solution and to their counterion selectivity. It also contains methods of synthesis and new concepts of charge stabilized polymer colloids and of polyelectrolyte ca talysis. The second part describes recent information on the properties and biological effects of already well-known natural polyelectrolytes such as heparin and DNA and recently developed polymers such as pyran and polyionenes. The effects of poly anions and polycations on normal and transformed cells as well as on acetylcholine receptors follow. This part is of particular interest to scientists involved in biological research.
